These bearings come in internal and external types. Internal bearings have an outer-ring ball groove ground to a spherical surface. This surface makes these bearings insensitive to misalignment, but increases raceway contact stresses, which cuts load capacity.

Externally self-aligning bearings have a spherical surface on the outside of the outer ring, which matches a concave spherical housing. External bearings have better load capacity than internal, but demand greater radial space.

We produced Self Aligning Bearings for over 10 years with much more experience. Range from Dia 10mm--100mm. Items from 1200--1220, 2200--2220, 1300--1320, 2300--2320...
